Pityriasis Rotunda

Pityriasis rotunda is a rare skin disease characterized by round or oval patches, localized mainly on the trunk, arms, and legs. The patches are usually lighter than the surrounding skin, but sometimes may be darker, and are covered by fine, adherent scales. It is very rare in caucasoids, common in Japanese and is also seen in South African blacks and West Indian black and Mediterrean area predominantly in Sardinia have been reported but it is seldom observed in Europe. We present the first two cases diagnosed from Turkey. There were well-demarcated circumscribed scaly plagues with a erythematous periphery and hypopigmented center on the trunk and proximal parts of upper limbs. Their skin phototype was III. Histopathologic examination revealed a moderate degree of compact hyperkeratosis without a granular layer. Complete clearing was observed with only emollients. (Turkderm 2010; 44: 99-101)
